Protein

Hydroxyacylglutathione hydrolase, mitochondrial

Gene

HAGH

Organism
Bos taurus (Bovine)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

Thiolesterase that catalyzes the hydrolysis of S-D-lactoyl-glutathione to form glutathione and D-lactic acid.By similarity

Catalytic activityi

S-(2-hydroxyacyl)glutathione + H2O = glutathione + a 2-hydroxy carboxylate.

Cofactori

Zn2+By similarityNote: Binds 2 Zn2+ ions per subunit.By similarity

Pathwayi: methylglyoxal degradation

This protein is involved in step 2 of the subpathway that synthesizes (R)-lactate from methylglyoxal.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Lactoylglutathione lyase (GLO1)
  2. Hydroxyacylglutathione hydrolase, mitochondrial (HAGH)
This subpathway is part of the pathway methylglyoxal degradation, which is itself part of Secondary metabolite metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes (R)-lactate from methylglyoxal, the pathway methylglyoxal degradation and in Secondary metabolite metabolism.
